The influence of silanes on the reaction of enones with cuprates has been examined using the title enone compound and Me2CuLi.LiI. In ether solvent the effect the effect of various silanes on the 1,4/1,2 addition ratio was minor. In tetrahydrofuran significantly increased 1,4/1,2 addition ratios and increased conversion of substrate was noted in the presence of silanes. Me3SiC1 proved to be the most
